Featuring a welterweight title fight between current champ Georges St-Pierre and former Strikeforce titleholder Nick Diaz, UFC 137 takes place Oct. 29 at the Mandalay Bay Events Center in Las Vegas.

The night’s main card airs on pay-per-view, though it’s not clear if Siver vs. Stout and Marshall vs. Vera will be part of the broadcast.

Siver returns to action after a hotly-contested decision win over Dennis
Wiman at UFC 132. The German striker is currently one of the hottest
commodities in the UFC’s lightweight division after having rattled off
consecutive wins over Wiman, George Sotiropoulos, Andre Winner and
Spencer Fisher.

Siver currently is 8-1 over his past nine fights, which includes a 7-1 mark
in the octagon. Along the way, he’s picked up four “Fight Night” bonuses
– two for the evening’s best knockout and one each for best submission
and best fight.

His opponent, five-time “Fight of the Night” winner Stout, returns to action
after picking up his first-ever “Knockout of the Night” bonus with a
vicious KO of veteran Yves Edwards. The result marked the
always-exciting Stout’s first-ever octagon finish and his first
knockout victory since a September 2007 win over Martin Grandmont under
the TKO banner.

The Canadian Team Tompkins product currently is riding a two-fight win streak and is 4-1 in his past five fights.

Marshall, meanwhile, likely finds himself in a must-win situation after opening his second career UFC stint with a UFC 128 TKO loss to Luiz Cane. A competitor on “The Ultimate Fighter 8,” Marshall earned three straight official wins to open his UFC career before being released from the promotion following a split-decision loss to Vladimir Matyushenko. After three-straight wins on the regional circuit, Marshall was brought back to the promotion in March.

Meanwhile, Vera may also need a win to remain with the world’s biggest MMA promotion. “The Truth” was already released from the promotion this past January following a loss to Thiago Silva. The defeat represented his third-straight loss, but Vera was offered a reprieve when Silva was later suspended for a failed drug screen. Vera, a former top heavyweight contender ,who’s 3-3 at light heavyweight, then was brought back to the promotion.
